Notes:In 1995, the U.S. Mint issued commemorative Half
Dollars, Silver Dollars and $5 Gold pieces as part of an effort to raise money to preserve the battlefields of America's
Civil War. The front of the Half Dollar features a Civil War drummer in
dress uniform standing in front of a wooden breastwork. The back of the
coin shows a cannon overlooking a large battlefield, illustrative of the
historic areas threatened by urban encroachment and development. The
legend on the reverse reads "Enriching Our Future By Preserving The
Past." The 1995-S Half Dollars were produced in both Proof and
Uncirculated versions.
